In 'thewfaucet y'of-:this inventionythe r-hotand cold'water'supply' lines pass throughvalves which are actuated "by a "cam whicheis'so -connected with the swing-arm V'spout''that'i'fhe Aposition of vthe spout determines the extent 'to-Whichl either or both fof' the valves is opened or shut. 'nthefpreferred arrangement' 'shown in lthe drawings the spout adapted "to swing throught an arcA only slightly less than 180 `andbo'thr valvesare closed when' the spout 'is swung "tor `the "extreme 'right i The' invention will be further described in vconnection with the-accompanying Vdrawings Yin --Which'Fig 1 Visan exploded'vew of the-faucet ing hotL and cold Wateryrespectively. The flow .of Ythe hot and v'Coldwater is controlled lbyvalves located inthe chambers-landt. The valve for ,regulation of V'the cold water-'fis identical with that shown for regulation of the hot water. `'The latter comprises the valve' stem `8 with the Ivalve 9 which seats on the valve seat I0 in the chambei'. The Valve is held in place by the nut I I which threads into the top of the chamber 4 and the spring I2 causes the rounded bottom of the valve stem to ride on the surface of the cam I5 and this in turn controls the amount that the valve 9 is lifted from the seat Il). The ring I8 serves as a guide to limit the side movement of the valve in the chamber 4. This guide may be omitted.

Hot water entering the boss 2 passes down through the valve chamber 4 and through the connection into the chamber 2I into which complementary taper so'that the 'spout -iitsfs'ii'uly .inlthe #chamber and no-wateres'capes `il'oetwe'eri its rWalls and the ibodyportion 22. l f

Figa illustrates various positions to which-'the swing-arm may be turned and these are desighated A, B, C, D, F and "G, respectively. `In

:the :positions A 'and' G both the lhot andfoold watervalves are closed. Inithe positions (Brand Cithe cold water valve is closed-and the ihot "water valve lis partially opened and Afullyv opened,

respectively. In the position D the hot and cold water valves are both open and may be wide open or only partially open. In the positions E and F the hot water valve is closed and the cold water valve is fully opened and partially opened, respectively.

The opening of the valve is controlled by the cam I5. When the unit is assembled the high portion of the cam 40 is located directly below the swing-arm 23. The cam turns with the swing-arm. When the swing-arm is turned to the position A (Fig. 3) the stem of the hot water 'from its seat.

valve located in chamber 4 abuts against the left- Ahand side of the raised portion 40 so that the swing-arm can be moved no further in this direction. Similarly, the stem of the valve in the chamber 5 for the cold water abuts against the right-hand side of the raised portion 40 when the swing-arm is moved to the position G, so that this is as far as the swing-arm can be turned in this direction.

As the cam is moved it raises and permits the lowering of the stems of both the hot and cold water valves which bear on diametrically opposite portions of the cam. To simplify the eX- planation, when one of the valve stems is pressed Y of the cam the valve closes against the seat in the valve chamber. No water can then pass through the valve into the swing-arm. On the other hand. v

when a thick or high portion of the cam i5, is moved under a valve stem, the valve is lifted The amount that the valve is opened depends upon the height of the portion of the cam which is under-the valve stem.

. 'Io facilitate understanding of the cam, in Fig. 4, the top surface is divided into sections which are lettered with the same letters used in Fig. 3.

For instance, the two letters A indicate the ysurfaces of the cam Which are below the respective valve stems when the swing-arm is in the position indicated as A in-Fig..3. The surface A Iadjacent the high portion 40 is below thestem ,of the hot water-valve and the opposite portion "of the cam which also bears'the letter A is below the stem of the cold water valve. Both portions of the cam lettered A are thin and, therefore, both valves are closed. When the swing-armV is -moved to the position B of Fig. 3 the stem of vthe hot Water valve rides up the inclined surface B and the hot Water starts to flow. The surface B below the stem of the cold water valve is on thesame levelas the surface A adjoining it and Y the cold water valve remainsclosed. When the -swingearni is moved to the position C the stem ofthe hot water valveis lifted further so that this valvefis wide open. The opposite surface C ision the same level as the adjoining surface B; so that the cold water valve remains closed. The surfaces D on opposite sides of the cam are of the same height and may be the same height asA the surface C on the left-hand side of the valve or a triflelower. Both valves are, theref-ore, fully or partially opened when the arm is in position-D (Fig. 3); The portions of the cam surface marked E, F and G correspond to the positions C, B and A on the cam, respectivelyfbut are on opposite sides of the cam and operate the opposite valve.

Thus it is seen that in this faucet the movement of the Yspout is utilized to regulate the amount and temperature of the water. 'I'he positions indicated in Fig. 3 are illustrative only Vand do not limit the positions to which th-e swingarm may be moved because the swing-arm may be turned to any position between A and G. Thus, the water may be turned olf entirely by swinging the spout to either side, and at the intermediate positions diiierent amounts of Water are obtained and the temperature of the water is controlled.

It is to be understood that the invention is not limited to the specific arrangement shown, as other types of valves and other means for operating the same may be employed. The faucet may be constructed of brass or other suitable material.

What I claim is:

1. A faucet for hot vand cold water which comprises a body portionl in which are two valve chambers and a chamber for the body of a swingarm spout, hot Vand'cold water lines leading to the' respective valve chambers, a. connection in said body portion between each valve chamber and the chamber forthe body of a swing-arm spout, a swing-ar-mvspout with a body whichnts into the body chamber, acam fastened to the bottom of said body and adapted to move with it,rand in each valve chamber a valve mounted on a valve stem and a spring which tendsl to seat the valve and causes thebo-ttom of the valve stem tov press on to-the surface of the cam and be operated .by its movement.

2. A faucet for hot and cold water, a chamber therein which is circularinl cross section and gradually tapers inwardly, a'swing-arm spout, the body of which fits snugly in the chamber, there being an opening in the bottom Vof the chamber and A-an extension on lthe bottom of the body eX- tending therethrough, abanov fastened to sai-d extensionand movable .'therewith, the upper portion Vofthe body being hollow, a groove which en- `circles the body at the bottom of the hollow por- REFERENCESV errno The following references are" of record Ainthe rile of this patent:
